By this arrangement it will be seen that I am enabled to quickly adjust the furnaces without dismantling them in any desired relation to each other, so as to heat two portions of a bar at any desired distance between said portions.

The burners 22 and 23 are provided with the stationary pipes 3l and 32, through which a blast of air is driven from any desired source to furnish the necessary supply of oxygen for burning the oii,which is conveyed to the burners in the pipes 33, the pipe 33 for the burner 23 not being shown. 'lo provide the air-supply for the burner2l, I extend from the pipe 3l the horizontal branch 34, into which is telescoped by a substantially air-tight joint the horizontal portion of an L-shaped air-pipe 35, which supplies air to the burner 2l. These air-pipes may be provided with such valves as are deemed necessary for controlling the passage of the air through them; but I have not deemed it necessary to illustrate these valves in detail, as they form no part of my invention.

To furnish oil to the movable furnace from the pipe 33, I place in the horizontal pipe 36, which connects the top of the pipe 33 with the burner 23, a T-shaped sleeve 37, which is screwed onto the ends of the sections of the pipe 36, so as vv,to permit the oil to pass from the pipe 36 into the T-shaped sleeve 37 and thence into the pipe 33, which is screwed into the sleeve 37 in the manner clearly shown. A valve 39, for controlling the admission of oil to the burner 22, is placedin the pipe 36 between the sleeve 37 and the burner. A horizontal pipe 40, having the valve 41 therein to control the admission of the oil to the burner 21, has screwed on its outer end the elbow 42, which has one end of the pipe 43 secured therein. The lower end of the pipe 33 has secured thereon the elbow 44, and the lower end of the pipe 43 has secured thereon a similar elbow 45, the two elbows 44 and 45 being connected by the short pipe 46, which is screwed into the said elbows, so that as the members 5 and 6 are moved relative to each other the sleeve 37 turning upon the sections of the pipe 36, the elbow 42 turning upon the end of the pipe 40, and the elbows 44 and 45 turning upon the pipe 46 will permit of the angular variation between the pipes 38 and 43 that is necessitated by the different positions of the two members. With the telescoping connections between the air-pipes and the swinging connections between the oil-pipes it will be seen that the air and oil supply'for the movable member 6 of the furnace will be maintained whatever distance may separate the two members.

It will be seen that by my invention Iprovide a furnace that is adjustable not only to vary the length of the heating-surfaces, but which is adjustable to furnish two heatingsurfaces of different distances from each other,

and with this furnace I am enabledto heat rods and bars in almost any way that may be necessary in the manufacture of machinery.

While4 I have shown my invention as em` What I claim as new, and desire to cover by Letters Patent of the United States, is-

1. In a furnace, the combination with the stationary furnace member, of the movable furnace member, said members having the surfaces 'upon which the articles to be heated are placed in substantially the same plane, adjustable oil and air pipe connections between said members, and means for moving said movable member in the plane of the said surfaces so that the articles can be heated at points different distances apart, substantially as described. y j

2. In a furnace, the' combination with the furnace member having a burner at one end thereof and the oil-pipe and air-pipe leading to the said burner, of the movable furnace member having a burner at one end thereof, the heating-surfaces of said members upon which the articles to be heated are placed being in substantially the same plane, the adjustable oil and air pipe connections be tween the air and oil pipes of the burner on the stationary member and the burner on the adjustable member, and means for moving said movable member in the plane of the said surfaces so that the articles can be heated at points different distances apart; substantially as described. j

3. In a furnace, the combination with the stationary furnace member having a burner at one end thereof, and the air-pipe and oilpipes leading to said burner, of the movable furnace member having a burner at one end thereof, the telescoping air-pipe connections between the burner on the movable member and the air-pipe for the stationary member, and the pipes 38 and 43 pivotally connected at both ends thereof between the oil-pipe on the stationary member and the burner on the movable member, all cooperating substantially as and for the purpose described.

4. In a furnace, the combination with the stationary furnace member, of the movable furnace member, burners for each of said members adjustable oil and air pipe connections between said members, and means for adj Listingl the movable member relative to the stationary member consisting of the screwthreaded rod secured to rotate in one of said l IOO members and cooperating with the screwthreaded aperture in the other of said members.

5. In afurnace, the combination with the stationary furnace member, of the movableY furnace member mounted on rollers, adjustable oi1 and air pipe connections between said members, andmeans for adjusting the mov-l base-plate to increase or diminish the breadth of the furnace-top.

7. In a furnace, the combination with the' base-plate, of the stationary ends, the sides provided with the segmental flanges overlapping the ends and 'pivoted thereto at 'their lower ends, and means for securing thesides in any desired position ofadjustment.

' 8. In a furnace, the combination 'withthei base-plate, of the stationary ends, the sides provided with the segmental flanges overlapV 4 ping the ends andA pivoted thereto at `their lower ends, and means for'securing .tihesidk-:as

inany desired position of adjustmentLconsisting of the segmental slots'insaid flanges concentric with 1;he"pivota1'` points. thereof andthe bo1ts'l9 passing through/said slots into the endssubstantially as and forfthe pur-y posedescrbed. y

9. A furnace of the class described,having a rectangular fire-box withan" oil-'burner'..lo-

cated so as tovdrect the flame inwardly frein one end nearone side, and "anothersimilar burner located so as to.directtheiiamein-v` wardly from the other end'neai` thefother side,and adapted to 'have a temporarywali..

extending between the centers of theends.
